To partition a potential hacker to attack your Linux server, he will first try to buffer overflow. In the past few years, buffer overflow is the most common form of security vulnerabilities. More seriously, the buffer overflow vulnerability accounts for the majority of remote network attacks. About partitions　　If a potential hacker attempts to attack your Linux server, he will first try buffer overflow. In

Protecting our wireless networks to the maximum extent is a matter of great concern to us. From which aspects should we manage and set them? Here we will introduce it to you. The purpose of reasonably protecting wireless access points is to isolate wireless networks from outsiders who are not authorized to use services. It is often easy to do. In terms of security, wireless networks are usually more difficult to protect than fixed wired networks, beca

A company named infoexpress believes that dynamic network access control (dnacc) technology can be used to achieve this. Network Access/Access Control Technology (NAC) generally includes hardware infrastructure or client software designed to protect network security. By using the P2P method, DNA c can change this mode,

The extensive use of wireless networks also brings about the security of wireless networks. Because wireless networks are different from wired network physical node access controllability, the security of wireless networks deserves our attention. For the current wireless network, we can improve the

processing, network management, and traffic control, this vpn-dedicated router provides a private management platform, enables secure and efficient communication. Take the di-740p model of the Broadband Router D-Link, the default Management address is 192.168.0.1, the Management port is 8080. Set the IP address of a computer and the router management address vro in the same network segment. For example, 19

In response to the various problems in network security, how we should solve, here is to tell us a truth, to start from the security aspect, this is the key to solve the problem. One of the outstanding problems with corporate wireless networks is security. As more and more c

As Wi-Fi continues to spread, its security issues are highlighted. 802.11 is the wireless LAN standard established by IEEE. Wi-Fi is a commercial 802.11 standard. Because the Wi-Fi Alliance early no mature security mechanism, resulting in the spread of the net people. This article provides security analysis for the hidden SSID mac binding WEP WPA WPA2 and its En

This article describes in detail how low-end and high-end routers think about network security, as well as the basic principles of routers. I believe this article will help you. Low-end routers and high-end routers are similar in usage. Why is the price so far different ?" In fact, this question is very good, and many friends who are not familiar with the product and technology will basically have similar q

Although firewalls are highly efficient in preventing network intrusion and have become a key factor in submitting Secure Web sites and services, all these security measures are achieved at a high cost. In short, the firewall limits performance and scalability. Because the firewall is an online device that may cause a single fault point, it will reduce the

, technically different from the traditional financial audit, because the computer stored information is electronic, easily modified, and can not be modified traces. To ensure that audit records are not modifiable, is the key to the evidence after the event. The business audit required by the listed companies in the US Symbian Act clearly requires the characteristics of an audit record that cannot be modified. At present, in addition to audit product

is also a very annoying messenger service to turn off, otherwise there will always be a message service sent online ads. Open management tools → Computer management → services and applications → service, turn it off when you see the useless. Step four, prohibit the establishment of an empty connection. By default, any user can connect to the server via a null connection, enumerate the accounts, and guess the password. We must prohibit the establishment of a null connection, the following two ki

network to send the MD5 of ciphertext and plaintext to server 3. The client and server use the DH algorithm for the 3DES or AES algorithm key exchange 4. After the server receives the suffix expression expression, decrypts, decrypts the MD5 value of the plaintext, compares it to the MD5 from the client, and then calls the Mydc.java function to compute the value of the suffix expression and sends the result
